A/C units are an important part of most homes and businesses in Singapore, so it’s important that you take care of them in every way you can.

Working air conditioners often tend to get neglected until they start malfunctioning or stop working altogether, and a malfunctioning air conditioner is something you can’t afford.

Before deciding if you should call in aircon servicing for your unit, here are five things that you need to be on the lookout for:

1. The aircon unit is leaking water.

This is the most common problem people deal with at work or at home, as well as the most annoying (mostly due to run-off that eventually weakens the concrete or the support for the A/C unit).

Why this is bad: Water accumulating inside the A/C unit can cause it to potentially ground and malfunction. Because stagnant water can be home to mold and algae, it can also trigger the allergic reactions of people in the room.

The cause: Leaking water is most likely due to a faulty drainage system.

2. The unit is not cooling as well as it used to.

Over time, your A/C unit will not be cooling as well as it used to, and you will need to set the cooling temperature at a higher level to keep it cooling the same way as before.

Why this is bad: Maximum capacity may overload the unit, which can shorten its shelf life and cause problems in the long run.

The cause: There’s a good chance the filter is blocked by cobwebs, dust, and debris. It could also be caused by broken parts that are not working properly. If you can’t seem t figure out on your own, it’s best to call an aircon maintenance expert.

3. The A/C output smells funny.

Even if you don’t see the output, you can definitely smell something coming from the A/C unit that should not be coming from there.

Why this is bad: This can often indicate other instances of disrepair in any of the unit’s parts or the wiring.

The cause: These can be carcasses of small animals to broken circuitry or wiring, both of which are enough reasons to call an air cooling maintenance company in Singapore.

4. The unit is really loud.

This is an equally common problem characterized by a loud “wailing” sound whenever it is switched on. If this is the case, you need to call aircon servicing as soon as possible.

Why this is bad: This can not only make it difficult for people at home or in the office to focus, it may also be a sign that something in the unit is not working properly.

The cause: Either the fan belt or the fan motor are not lubricated well enough, or are in severe need of replacement, which means that you should contact an aircon servicing or aircon repair service in Singapore right away.

5. There’s smoke coming out.

You can see visible smoke coming out of the air conditioning unit. If this is the case, turn your unit off immediately and unplug it. Call an aircon repair service as soon as possible for a complete overhaul.

Why this is bad: It may explode, especially if you don’t call aircon servicing in Singapore right away.

The cause: The unit may have short-circuited or may have broken circuitry or wiring, which can be dangerous.
